All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your data is not diagnostic of hyperthyroidism. Unintended weight loss warrants evaluation by your doctor.
Wish you good health!

A condition called Plummer's disease can be caused by a hyperfunctioning thyroid nodule (thyroid adenoma) which does not follow normal hormonal mechanisms, and can suppress TSH disporportionally to the elevated T4 result. See a endocrinologist for a more detailed workup.
